Embodiment 2

[0039] according to Figure 1-2 The hydraulic flexible robot joint shown is different from the first embodiment in that: the power mechanism is composed of a hydraulic pump motor 14 and a hydraulic pump 21, and the actuator also includes a telescopic bellows 3 and an end plate 23 And the end plate connecting plate 25, the power transmission unit is provided with three groups; the hydraulic pump motor 14 is connected with the hydraulic distribution part through the hydraulic pump 21; the hydraulic distribution part is the hydraulic distribution valve 13, and the hydraulic distribution valve 13 is connected to the hydraulic pump 21; the hydraulic distribution valve 13 is provided with a circuit interface 19 and an output interface 20, the output interface 20 is connected with an output oil pipe 18, the circuit interface 19 is connected with a circuit oil pipe 17, and the circuit oil pipe 17 A plurality of hydraulic pipe tees 10 are connected to it, and the return oil pipe 17 is ...

Embodiment 3

[0043] according to figure 1 The shown robot includes a hydraulic flexible robot joint, and a manipulator 1 is connected to the front end of the hydraulic flexible robot joint through a servo motor 2 .

[0044] In actual use, when the hydraulic cylinder ram 6 moves, the angle of the end plate 23 can be directly adjusted, and the rotation of the servo motor 2 makes the manipulator 1 easier to operate; The front end of the cylinder jack rod 6 is closely matched with the hydraulic cylinder body 5, while the diameter of the rear end is reduced according to a certain ratio to match the sealing ring 22. The return oil pipe 17 is arranged in the diameter of the telescopic bellows 3, and passes through the hydraulic pipe tee 10, respectively. Transmission to each hydraulic cylinder block 5, when the hydraulic pump motor 14 works, the hydraulic pump 21 is driven to generate high-pressure oil fluid, which passes through the hydraulic distribution valve 13 through the hydraulic oil circu...

Abstract

The invention belongs to the field of robots and particularly relates to a hydraulic flexible robot joint and a robot. The hydraulic flexible robot joint is composed of a power mechanism, a hydraulicallocation part and multiple sets of execution units. Each set of execution unit comprises organic arrangement of an execution mechanism of series-connected hydraulic cylinders which is composed of multiple hydraulic cylinder bodies. The flexible robot joint which can be prolonged or shortened optionally as required is provided. Each work is flexibly completed through the robot which is connectedwith a manipulator through a servo motor in front of the flexible robot joint.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a hydraulic flexible robot joint and a robot. Background technique [0002] A robot is an automatic machine that can imitate certain human activities. Generally, it can realize actions such as walking and operating production tools, and can work instead of humans in environments that humans cannot adapt to. Modern robots are equipped with electronic computers. Through programming, they can have a certain degree of artificial intelligence, such as recognizing language and images, and making appropriate responses. [0003] Although the robot joints in the prior art have balanced and stable transmission, higher motion transmission accuracy, reliable technology and processing technology to provide stable and reliable life, they have the disadvantage of not being flexible enough to adjust. Contents of the invention [0004] The invention provides a hydraulic flexible robot joint ...
